Dropout events are dramatic decreases in radiation belt electron populations that can occur
in as little as 30 minutes. Loss to magnetopause due to a combination of magnetopause …

Energetic electron dynamics in the Earth's radiation belts and near‐Earth plasma sheet are
controlled by multiple processes operating on very different time scales: from storm‐time …

Auroral zones are regions where, in an average sense, aurorae due to solar activity are
most likely spotted. Their shape and, similarly, the geographical locations most vulnerable to …

Drift orbit bifurcation (DOB) has been suggested to play a major role in the loss and transport
of radiation belt electrons since it violates the second adiabatic invariants of particles and …

In response to a solar wind dynamic pressure enhancement, the compression of the
magnetosphere generates strong ionospheric signatures and a sharp variation in the …

Understanding of Earth's geomagnetic environment is critical to mitigating the space
weather impacts caused by disruptive geoelectric fields in power lines and other conductors …

The response of the Earth's magnetotail current sheet to the external solar wind driver is
highly time-dependent and asymmetric. For example, the current sheet twists in response to …

Radial transport of energetic electrons is one of the key processes responsible for the
variability of the outer radiation belt. This transport amounts to a violation of the drift motion …

Quasilinear theories have been shown to well describe a range of transport phenomena in
magnetospheric, space, astrophysical and laboratory plasma “weak turbulence” scenarios. It …

Electrons with energies≥ 40 keV can be found at low density in many different regions of
Earth's magnetosphere. A litany of fundamental questions in space physics have focused on …
